From f5c90e85dc77669a55fecfb593bb8e7f47374ee2 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Mon, 28 Apr 2008 02:15:24 -0700 Subject: [PATCH] lxfb: clean up register definitions - Rename various bitfield defines to match the data sheet names. - Rename DF_ register definitions to VP_ to match the data sheet; ie, DF_PAR -> VP_PAR. - for GP/DC registers, rather than defining to specific addresses, use an enum to number them sequentially and just multiply by 4 (bytes) to access them (in read_*/write_* functions). - for VP/FP registers, use an enum and multiple by 8 (bytes). They're 64bit registers. Signed-off-by: Andres Salomon Cc: "Antonino A.
